Self-help books by Kris Radish. A brief review

Kris Radish is not merely a well-known professional journalist in the US, she is also a person of gift and courage.
She is open to new experiences, brave and frantically creative.
Her self-expression is a path of the truth, as well as a realm of wonders.
Apart of her numerous columns and investigations, interviews and shows, podacsts and essays, she has written a bunch of self-help books based on her intimate knowledge of some popular theories, as well as her own extensive experience.
In a book labeled as 'The Birth Order Effect' she tackles the topic of a typology based on a family birth order.
She sees the links between the position in a family and a human character, dividing people into 4 types.
In which way is this idea similar to the idea of typologies based on the blood type?
Both are under a fire of heavy critique, and both seem to be quite efficient in the end.
The way a child perceives the world is partially defined by their position in a family.

The descriptions of types in this book are vivid and realistic, so this typology may be applicable to each country.

A timeless style, strong argumentation and concern for the reader - these traits make her writing unique, bright and useful.
